Background: Malnutrition in patients with chronic obstructive pulmonary disease (COPD) is common and associated with poor prognosis. Nutrition interventions are necessary, but there is a lack of evidence regarding the effectiveness of tailored nutrition advice. Objective: This study investigated whether tailored nutrition counseling could improve dietary intake, nutritional status, functional outcomes, and health-related quality of life (QoL) of malnourished outpatients with COPD. Design: We conducted a randomized controlled trial in which participants were randomly assigned to either the intervention group (IG) or the control group (CG). Participants/setting: One hundred and twenty malnourished outpatients with COPD participated in the study between May and November 2017 at the National Lung Hospital, Hanoi, Vietnam. Intervention: The IG received tailored nutrition counseling once per month for 3 months based on a specifically developed written nutrition resource for COPD. The CG received the same educational resource at baseline without any discussion. Main outcome measures: The main outcome measures were energy and protein intakes, body weight change, nutritional status (Subjective Global Assessment score), muscle strength, and QoL. Statistical analyses: Differences between groups before and after the intervention were assessed using two-way repeated measures analysis of variance. Generalized estimating equation modeling was used to investigate the differences between groups over time. Results: At baseline, there were no significant differences in outcomes of interest between the two groups. After 3 months of intervention, time–intervention interactions for energy intake, protein intake, and body weight change were significant (945 kcal/day, 95% CI 792 to 1,099 kcal/day, P<0.001; 50.0 g protein/day, 95% CI 43.9 to 56.1 g protein/day, P<0.001; and 1.0 kg, 95% CI 0.5 to 1.5 kg, P<0.001, respectively). Subjective Global Assessment scores improved in the IG and wo

Background: Malnutrition is common in patients with COPD; however, little is known about its impacts on health-related quality of life (QoL) among patients with COPD. This study aimed to explore the nutritional status and dietary intake among outpatients with COPD in Vietnam and its possible associations with QoL. Methods: A cross-sectional study was carried out in COPD outpatients visiting the COPD management unit at the National Lung Hospital, Hanoi, Vietnam between May 2017 and July 2017. Consecutive outpatients with a confirmed diagnosis of COPD were recruited with written inform consent. The nutritional status of participants was assessed using Subjective Global Assessment (SGA), and dietary intake via a 24-hour recall interview. The St George Respiratory Questionnaire (SGRQ) for COPD was used to investigate the participants’ QoL. Sociodemographic and clinical data were extracted from hospital records. Results: Of 168 COPD outpatients involved in the study, three-quarters (74.4%) were diagnosed as malnourished (SGA B/C) and 81.5% reported unintentional weight loss. Most of the patients did not meet their estimated energy and protein requirements (85.7% and 89.9%, respectively). Malnutrition was significantly associated with disease severity (P=0.039) and ratio of protein intake to estimated requirement (P=0.005). QoL was low for all levels of malnutrition or disease severity, with well-nourished participants and those with less disease severity having better QoL (P=0.006 and P<0.001, respectively). With an extra meal per day, the odds of having malnutrition decreased 5.6 times (P<0.05) and the total SGRQ reduced 3.61 scores (P<0.05) indicating a better QoL. Conclusion: Malnutrition and weight loss are prevalent among COPD outpatients. Most of the patients had inadequate dietary intake and low QoL. Nutrition counselling including increasing the number of meals per day with a focus on energy-and protein-rich foods may help improving nutritional status and QoL
